6. If the cluster is running with only one node, bring up the other cluster nodes. Enter the vxdg
list command on each node to display the shared disk groups.
Verifying Existing Shared Disks
If you are upgrading from a previous release of VxVM, verify that your shared disk groups still
exist.
To verify that your shared disk groups exist, complete the following steps:
1. Start the cluster on all nodes.
2. Enter the following command on all nodes:
# vxdg -s list
This command displays the existing shared disk groups.
Converting Existing VxVM Disk Groups to Shared Disk Groups
This section discusses the procedure to upgrade from VxVM 3.x to VxVM 5.0.1 and to convert
existing disk groups to shared disk groups.
To convert existing disk groups to shared disk groups, complete the following steps:
1. Ensure that all systems that are running are part of the same cluster.
2. Start the cluster on at least one node.
For a two-node cluster, start the cluster on one node; for a four-node cluster, start the cluster
on three nodes.
3. Configure the disk groups:
• List all disk groups, use the following command:
# vxdg list
• To deport disk groups to be shared, use the following command:
# vxdg deport disk_group_name
• To import disk groups to be shared, use the following command on the master node:
# vxdg -s import disk_group_name
This procedure marks the disks in the shared disk groups as shared and stamps them with
the ID of the cluster, enabling other nodes to recognize the shared disks. If dirty region
logs exist, ensure that they are active.
• To display the shared flag for all the shared disk groups, use the following command:
# vxdg list
The disk groups are now ready to be shared.
4. If the cluster is only running with one node, bring up the other cluster nodes. Enter the vxdg
list command on each node to display the shared disk groups. This command displays the
same list of shared disk groups displayed earlier.
Upgrading in a Clustered Environment with FastResync
In order to upgrade in a clustered environment with the FastResync option, you must perform the
procedure discussed in this section in addition to the procedure discussed in “Converting Existing
VxVM Disk Groups to Shared Disk Groups” (page 39).
